一、加宽延长渠道井水流入渠道后,水温高低与渠道长短,气温高低有很大关系。所以,对于粘土性稻田,可采取延长渠道措施来提高水温。在修筑稻田渠道时,除加宽水渠外,还可修筑迂回渠道,或在坡度大,水流急的地方增设跌差,并做到及时割去田间及渠道两旁杂草,以增加灌溉水流的日晒时间和扩大日晒面积来提高水温。二、设晒水池在水田井附近选择有利地形设置晒水池,并设溢水口,使表层温水进田。池内水层不 First, broaden the channel to extend After the well water into the channel, the level of water temperature and channel length, the temperature has a great relationship. Therefore, for clay paddy, extension measures can be taken to increase the water temperature. In addition to widening the water channels, we can also build circuitous routes in the construction of rice-field channels or add drop-off places in places where the slope is steep and the water is in a rush. We also need to cut off weeds on both sides of fields and channels in a timely manner so as to increase the flow of irrigation water. Increase your temperature by basking in the sun and by expanding the sunburn area. Second, set sunbathing Well in the vicinity of the paddy well selection of favorable terrain to set the sun pool, and set the overflow port, the surface warm water into the field. Pool water is not
